3. It is a precursor for many tungsten compounds. It is used in tungsten plating, purification of tungsten, and olefin polymerization. It is also used as petroleum catalyst, and in intelligent glass. It can be used for deoxygenation of epoxides and as a reagent in organic synthesis.
Flammability and Explosibility
Notclassified
Purification Methods
Sublime it in a stream of Cl2 in a high temperature furnace and collect it in a receiver cooled in a Dry Ice-acetone bath in an inert atmosphere because it is sensitive to moisture. It is soluble in CS2, CCl4, CHCl3, POCl3, *C6H6, pet ether and Me2CO. Its solutions decompose on standing. Good crystals can be obtained by heating WCl6 in CCl4 to 100o in a sealed tube, followed by slow cooling (tablets of four-sided prisms). Store it in a desiccator over H2SO4 in the dark.

Check Digit Verification of cas no
The CAS Registry Mumber 13283-01-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,8 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13283-01:
(7*1)+(6*3)+(5*2)+(4*8)+(3*3)+(2*0)+(1*1)=77
77 % 10 = 7
So 13283-01-7 is a valid CAS Registry Number.

Kinetic study of Hubnerite (MnWO4) chlorination
Fouga,Taddeo,Bosco,Bohé

The kinetics of Argentinean Hubnerite (MnWO4) chlorination using gaseous chlorine as chlorination agent was studied between 750 and 950 °C. The relative mass change during the chlorination reaction was continuously monitored using a high resolution thermogravimetric system. The starting temperature for the reaction of the manganese tungstate with chlorine was determined at about 650°C. The influence of gaseous flow rate, sample mass, chlorine partial pressure, and temperature on the reaction rate was analyzed. The dependence of the reaction rate with sample mass clearly indicates that the reaction is not occurring under chemical control, so the reaction proceeds under mixed control for sample masses greater than 0.5 mg. In those conditions, an apparent activation energy of 198 ± 9 kJ mol-1 was obtained with an isoconversional method. Concerning the influence of chlorine partial pressure, it was determined that pressures greater than 35 kPa do not modify the kinetic regime. For the experiment at 850°C, it was found that the chlorination rate was proportional to a potential function of the partial pressure of chlorine whose exponent is around 0.85. Finally, a global rate equation that includes these parameters was developed.
